System apps are applications that come pre-installed on an Android device, usually by the manufacturer or carrier. These apps can include anything from browser and email clients to social media and games. Some system apps are useful, while others may be unnecessary and take up space.
The process of uninstalling system apps can vary depending on the device and Android version. On some devices, users can disable or uninstall system apps through the settings menu. Rooting the device can also provide more flexibility in uninstalling system apps, but it can also void the warranty and pose security risks.
